Wall molding linear-foot estimate

Estimate for rectangular molding frames.

Estimated quantity133.76 linear feet

Divide by 7.87 ft (240 cm stick) and round up for the number of sticks.

Formula & assumptionsframe_count * 2 * (frame_width_inches + frame_height_inches) / 12 * (1 + waste_percent / 100)

Assumes identical rectangular frames. The waste allowance is editable. The estimate does not optimize cuts or include separate rails, baseboards, or other trim.

Overview

Off-White is a white warm white with a warm (yellow) undertone and a calculated LRV of 80.9. With SW Pure White trim the molding has almost no contrast, so the molding reads through shadow alone (a tone-on-tone look) (contrast ratio 1.03:1).

Picture Frame layout on a 15 ft living room wall

Molding over the full wall height, upper and lower rows divided by a chair rail. On a 15 ft wall with an 8 ft ceiling this gives 6 frames per row, each 25.3 in wide, with 50 in upper and 21 in lower frames. The layout uses about 45.82 m of 2.5 cm molding, or 20 sticks of 240 cm, including 10% waste. Center the layout on the sofa or TV rather than the wall when furniture is off-center.

Building the picture frame pattern

Each frame is four pieces of 2.5 cm molding with 45 degree miters. Set the frames out from the center of the wall, keep every gap equal, and let the margins at the corners match the gaps.

Painting molding in Off-White

Warm whites keep molding soft and traditional. Match the trim to the wall for a calm look, or use a cleaner white on trim to sharpen the outlines.

Questions

How much molding do I need for a 15 ft living room wall with picture frame frames?

About 45.82 m (150 linear ft) including a chair rail and 10% waste, which is 20 sticks of 240 cm. That assumes 6 frames per row, 25.3 in wide, on an 8 ft ceiling.

Is Off-White warm or cool?

Off-White has a warm (yellow) undertone and reads as a white warm white. Its calculated LRV is 80.9, so it reflects a lot of light and keeps molding shadows soft.

How high should the chair rail be in a living room?

About one third of the ceiling height: 32 in on an 8 ft ceiling, 36 in on 9 ft and 40 in on 10 ft. Center the layout on the sofa or TV rather than the wall when furniture is off-center.
